TRANSPORT & STORAGE
General
sera products are checked for perfect condition and function previous to shipment.
Check for transport damage immediately after arrival of goods. If damage is found, this is to be reported immediately to the
responsible carrier and the manufacturer.
Storage
An undamaged packaging protects the unit during storage and should only be opened when the product is installed.
Proper storage increases the service life of the product and includes prevention of negative influences such as heat, moisture,
dust, chemicals etc.
The following storage specifications are to be obsered:
• Storage place: cool, dry, dustfree and slightly ventilated
• Storage temperature and relative air humidity see Chapter „TECHNICAL DATA“.
• The maximum storage time for the standard packaging is 12 months.
If these values are exceeded, metal products should be sealed in foil and protected from condensation water with a suitable
desiccant.
Do not store solvents, fuels, lubricants, chemicals, acids, disinfectants and similar in the storage room.
WARNING
Observe and follow the safety instructions by all means.
See the additional instructions „SAFETY INSTRUCTIONS“.
Man, machine and environment are endangered if the safety instructions are not observed.
SI02
Transport
The unit should only be transported using suitable lifting gears. Take into account the
weight of the unit and the load-bearing capacity of the means of transport.
The transport is carried out lying down.
Example::
Lift by means of a tie-bar (not included in the scope of supply).
Lead the carrying belts through the transport holes (1) and lift.
ATTENTION
Be careful when lifting the system. Pay attention to the center of gravity! Fasten the
system sufficiently!
ATTENTION
Do not place the system on the collecting basin while working!
If this note is not observed, the drain plug of the collecting basin may break off.

Symbols which are directly attached to the pump, e.g. arrows for direction of rotation or symbols for fluid connections
are to be observed and kept in legible condition.
Materials
The materials used are stated in the order confirmation and the product description.
Water quality
ATTENTION
Water used for start-up, maintenance and closing down must be similar to drinking water, i.e. chemically neutral, free from
solid and suspended matters and disturbing ion concentrations.
Note the compatibility of the chemical with water and take appropriate measures, if necessary.
Pay attention to the safety data sheet of the medium.
PRODUCT DESCRIPTION
8www.sera-web.com
The chemical is dosed by diaphragm pump(s). The conveying capacity of the pump can be set at the manual stroke length adjust-
ment. Depending on the design of the dosing pump, an additional automatic dosing is possible via pulse or analogue signals.
The piping on the pressure side consists of a taper seat non-return valve and a ball valve as end connection. The pump is pro-
tected against overpressure by an overflow valve. A drain ball valve for evacuation/pressure relief is fitted in the pressure pipe.
The pump and the corresponding fittings are mounted on a wall mounting plate with collecting basin.

PRODUCT DESCRIPTION

Diaphragm pulsation damper (pos. 200)
The chemical is dosed by means of an oscillating positive dis-placement pump. A pulsation damper can be integrated in the
pressure pipe for smoothing the pulsating flow of the pump.
ATTENTION
Whether a pulsation damper must be installed or not, de-pends on the design of the overall system and must be determined
from case to case!
Decisive factors are, among others, the pump size, the pipe geometry (length and diameter), pipe losses, the geo-detic
height to be negotiated and the opening pressure of injection fittings (which might be present) resulting from the spring
load.
The following possibilities are given for the pump series CVD2:
• Installation of a pulsation damper in each dosing leg and thus an independent operation of the pumps for different applica-
tions.
• Connection of the dosing pumps through the additional option “Connection of the pressure side of pump 1 and pump 2”
and installation of a common pulsation damper.
• Connection of the dosing pumps through the additional option “Connection of the pressure side of pump 1 and pump 2”
and installation of a common pulsation damper in each dosing leg. This enables a 100% standby opera-tion of the dosing
pumps. (Connection of pressure side only possible on left con-nection N1).
Piping on the suction side (pos. 300, pos. 350)
The basic unit can be fitted with a piping on the suction side as option. This piping includes a ball valve as stop valve and a dirt
trap.
The suction sides of each pump at CVD2 are separated from one an-other so that the medium can be taken from different barrels.
The suction sides of the pumps can be connected when a fur-ther option “Connecting conduit on the suction side of pump 1 and
pump 2” (pos. 350) is added.
Piping overflow relief valve (pos. 400)
When the overflow valves open, the medium can be led back into the suction pipes via return pipes.
ATTENTION
This option may only be used when a multifunction device (pos. 450) is mounted, or when the backflow of the medium into
the corresponding tank is not hindered by a foot valve or simi-lar in the suction pipe.
Inobservance of this note may result in damage to the sys-tem, the pump or adjacent system parts.

hose)!

Splash guard (pos. 500)
A splash guard is available as option to protect the operating personnel against chemical splashes which may occur due to
damage on the system. The splash guard consists of three parts. The side parts are fixed, the front part is removable.
Terminal box (pos. 600), socket (pos. 650 / 660) and main switch (pos. 610)
The system can be fitted with a terminal box or a socket or a main switch as transition points for power connections or a signal
exchange.
Leakage sensor (pos. 700 / 710)
A magnetic float switch (pos. 700) or a leakage sensor (pos. 710) detects leakages at the system. This optional device can be
integrated in the collecting basin.
ATTENTION
The magnetic float switch (pos. 700) is not approved according to WHG!
Stand for floor mounting (pos. 800)
The system is installed on a mounting plate for wall mounting as standard. A stand for floor mounting is available as option if
there are no possibilities for wall mounting at the installation site.
